TITLE: GCN CIRCULAR NUMBER: 1184 SUBJECT: GRB011130 (=XRF011130): Scheduled Target of Opportunity DATE: 01/12/08 09:28:31 GMT FROM: George Ricker at MIT GRB011130 (=XRF011130): Scheduled Target of Opportunity Observation with Chandra X-ray Observatory G. Ricker, P. Ford, G. Monnelly, N. Butler, R. Vanderspek (MIT); and D. Lamb (U.Chicago) on behalf of the Chandra ToO Team and the HETE Science Team write: On 10 December, from 00:38 UT - 09:27 UT, the Chandra Observatory is scheduled to observe the field of the X-ray rich gamma-ray burst XRF011130 that was localized by the HETE satellite (Ricker et al., GCN1165). The revised error circle for XRF011130 (Ricker et al. GCN1178) fits completely within the field-of-view of the ACIS-I array on Chandra. Special arrangements have been made by the Chandra Science Center to expedite the pre-processing of the data from our observation, so that the TOO Science Team should be able to carry out the accurate astrometry needed to establish accurate locations of the brightest X-ray sources in the HETE field within a few hours of receipt of data on 10 December. Assuming that the observation takes place as planned and that the bulk of the data are received during the morning on 10 December, the TOO Science Team will strive to disseminate the RA, DEC, and relative intensity for the 10 brightest X-ray objects in the field by GCN Circular as soon as possible -- hopefully within 12 hours after the observation is completed.
